I have a pair of Etymotic ER-4S that haven't been touched in years and years. It finally dawned on me that I should sell them and let someone else enjoy them. They were mainly used on airplanes and a little bit at home. I am still on my original pair of rubber eartips! As you can hopefully see in the pictures, there are extra foam tips, rubber eartips, a jack adaptor to use with a standard headphone jack, etc. EVERYTHING that came with them when new, including the inner and outer box. Feel free to ask for additional pictures or any other information that you would like.
